Release Notes: This release fixes a bug in bitarray that potentially impacted iterators. Users of genset_iter and gensetdyn_iter should upgrade.
The release also adds the skaclient3 and skaclient4 frameworks, for even more channels of communication between the client and the server.
The minor version bumped because the skaclient protocol has changed, and one header file has been removed.

Release Notes: This release fixes a few bugs in automatic sysdeps determination (which only appeared with certain combinations of Linux kernels and libc versions). It also updates the leap second table to include the June 2012 leap second.
